i'm trying to boot an ubuntu 10.04 system with encrypted root partition,
suddenly unable to.  i'm typing the passphrase correctly, as i see "Key
slot 1 unlocked" on the console, but it is then followed by:

cryptsetup: unknown fstype, bad password or options?
Device sda5_crypt is busy.
Device sda5_crypt already exists

and then i am asked for the passphrase again.  after i type it again i
am told "cryptsetup failed, bad password or options?"

after a third time i receive the same message but then after about a
minute i am told "no init found" and dropped to a Busybox shell.

sounds like my disk suddenly crapped out or something, what kinds of
remedies are available?  thanks
